Welcome to Blockchain 101!
Tell us what brought you here: transactions, distributed records, consensus, smart contracts, or deciding whether a blockchain is useful for a particular application.
Ask foundational questions and compare use cases with ordinary databases. Use test or public examples, and never share wallet recovery phrases, private keys or credentials. Keep discussion focused on the technology and course content.
Reply below to introduce yourself or ask your first question. For a new topic, start a separate post with a clear title and the lesson reference. Suggestions for improving the course are welcome, too.
